circular motion- movement of an object at constant speed with a fixed radius.
Also has rotation where an object turns around on an internal axis.
The fomula is v=rw.
Axis- straight line around which rotation takes place
Gravity & Weight-(newtons universal gravitation) fire a cannonball & it will eventually fall back to earth.
if you fire a cannonball at the right velocity it will travel around earth always falling beacause of the gravitational field but never reaching earth.
Equations f gravity.=gm*m squared/d squared
friction- surface resistance to relative motion
static friction-o< f static <m Fn
Kinetic friction force = Mk*Fn
Coulombs law- relationship among electrical forces charges and distance.(electric forces can be attractive or repulsive.)
Repulsive-positive and positive charge or negative and negative charges
Attractive- positive & negative charges discovered by french scientist. Q= charge
